Sorry if this is in the wrong forum but there doesn't seem to be one for wood. I grabbed this earlier and think it is a cigar box. I am struggling to find any reference to superba other than Juan Lopez superba cigars it's about 20cm long.
I see Sir Walter Raleigh cigars also using "superba." https://www.cigar.com/p/sir-walter-raleigh-coronas-superba-c-1950-cigars/1503477/ Debora
